EDWARD J. RUETII, oF CLEVELAND, onio LIGHTING FIXTURE My invention pertains to a light fixture.` The adaptation of the inventionexemplifiedby the drawings shows its use in associationl with an electric lamp socket.

My long experience with the lighting fixtureindustry caused me to become familiar not. only with marketed constructions, but also with a series of patented forms including those illustrated iny vAndersen No. 1,114,571, 10, Andersen No. 1,171,013, Harris No. 1,332,214, Wanbaugh No1,495,826 and Robinson No. 1,588,267. A

One obj ect of myinvention has been to de sign a screwless fixture. Another object is 1,5,s to provide' aixture with a lowerend o-f its globe suspending holder so narrowed in one dimension that relatively transverse projections intended actually to support the globe, may be successively inserted into the neck of 2Q the globe preparatory to having theglobe gravitatio-nally suspended thereon. Further objects have been to contrive a duplex provision' against undesirable displacement of a cover either upwardly 'or turnably andl inci- 2@ dentally sol that: the meansr for preventing A displacement of thecoverupwardly necessar-KV ily causes the cover to. limit a lifting displacement of'the gl'obe from the holder. A generali object has` beenthe de sign of a light- '30 ing fixture which combines intrinsic merit with commercial merit, in the sense,that it is easy to' assemblel and adjust so that it` will effectively exercise its function while including,Y apart from' a standard type of electric socket and globe, only two stampedy pieces which are simple and economical of manu-v facture. It is to be realized .that thevscope of my invention comprehends many equivalentV constructions. The showing of the drawingand the particular description are merely a specificexemplification of a plurality of mechanical embodiments andarrangements; Advertingto the drawing: v 455 Figure 1 is asideelevation of'an' improved lighting fixture embodying my inventions, partlyv broken away to show certain detailsin axial section.

Figure 2 isrnainly a vertical section on line .5.-0 ofFigure1partly shown inelevatic-n Application mea Aprile, 1929. serial Nb. 351,856.

and with twoelements additionally shown in alteredl positions by dot and dash lines.

Figure 8 is a horizontal section on line 3-3 of Figure 2 looking upwardly as'indicated by the arrows. f f

Figure 4 is a plan viewv on reduced scale ofv one art. v.,1 f As illustrated, the xtureis rigidly secured 1n any appropriate manner toa ceiling 1i and comprisesadjacent4 thereto a hollowl metal` stampingv 2 which is integrally constricted in a downwardly direction at-S and lthenl again widened or flared at 4.11 Where the-'sections ,3* and 4 merge the primary support2 is provided interiorly with an aperturedpartition 5 yagainst opposite sides ofwhicha twopart electric lightv socket 6 is clamped.v The two parts of' the socket Gimay be infscrew threaded vconnection withr each other, but` since that type of connection is common in the art it has not been illustrated. incandescent lamp `7 is detachably secured in the socket.

ContinuingI downwardly the; lower end of f the section 4 is flanged, but instead of being annularl itis' designed', as shown in Figurej, to comprisetwo concentric diametrically opposite arcuate portions 8A and twov diametricallyopposite straight and parallelgportions 9 toy constitute one of the features of myin. vention. It is interpolated that the horizonf tal cross-sectionalshape of the fixture is'of novconsequence and that while-'it is shown of mainly circular cross-section,for the purpose of economy in commercial production, it might be of any desired polygonalr shape.vv Since fixtures are,` however, usually round, my provision. of'one or more flat portions- 9: does constitute a feature of highly meritorious consequence. kPremising association' with a roundv fixture, the number of flat por-V4 tions 9 of the depending flange is manifestly variable at the willrof the manufacturer withl consideration of cost. j As exemplied, the. two fiat portions 9 are each fashioned midway with an outwardly projecting burr 10. to serve the purpose of4 a yielding detent or catch, as will be hereinafter explained. The burrs 1() might instead, 0r additionally, be, provided,

has in consequence an oblong or inverted T-V shape so narrowed in one dimensionthat rel` atively transverse projections may be successively'insertedfinto tlieneckI of a globe preparatory to having the latter gravitationally suspended thereon. The outward borders of the' `wider and arcuate diametrically opposite portions of the ledge .merge with two depending somewhat longer flanges 13 which terminate as outwardly flared ledges 13a, upon which opposite sides of the constrictedneck 14, of a globe 15, may rest when the upper end ofthe globe' is lcaused partially to enclose the flanges 13 successively as suggested by the upper Yend of the globes dotted line position in Figure 2. The upper rim 16 of the; neck of the optionally 'shaped as shown..

Functioning'so aste accomplishv a realiza-` tion of certain outstanding advantages of my invention, is a round cover 17, which includes a fiat top 17a fashioned with a central opening lcorresponding in shape and nearly in size to the planefigure defined by the flange composed of the Vtwo portions 8 and the two portions 9. Accordingly, as'shown in Figure 4, the opening 18 is dened by two opposite arcuate-edges 19 and bytwo opposite straight edges`20, the edges 19 being adapted' to be juxtaposed to the curved portions 8 and the edges 20'to the straight portions 9 respectively. Bythis arrangement when the cover'17 is inthe position shown in Figure 1 its turning movementwill be prevented by reason ofthe juxtaposed flat surfaces, as will bel readily understood. Prior to seating that portion of the top of the cover, which borders its peculiar opening 18, upon the ledge 11 its edges 20 mustbe sprung over the burrsy 10, which, because of the resiliency of the metal,

` will yield slightly in an inward direction andafterwards again spring out, as appears i inn Figure 1, therebypreventing,upward displacement of the cover vuntil somanipulated.

The bordel' of the coverA top continues down-V wardly as a short flange F21 thence outwardly asa narrowfledge 22 adapted to rest on the rim 16 'of theglobe-'and thence againdown- Wardlyas a longer flange 23, which very closely approaches or may. alternatively con.

tact the top of the globe when the cover top restsupon the ledge l In this manner the emplaeed cover additionallyserves to resist globe may be,

l by` said holder and having itsmargin'partialupward tilting of the globe and certainly to i prevent avtilting to such an extent as would permit its detachment from the ledge 13a.

My lighting fixture is ofy Outstanding sirn-A plicity, not only as to structure and number of parts, but in respect to its functionating assembly. While the globe 15 is being mounted in place, as indicated by its broken line .position in Figure 2,-v the. cover may be lifted to seine non-interfering position, as for instance, to that yindicated by the broken llines which, in Figure 2, define its outline.

I claim 1. In combination, a globe having a constricted open end, a holder including circumferentially spaced flanges insertible in vand adapted to support said globe, 'said holderVK being fashioned intermediately `of its ends sov with a substantially vertical flat surface, and' a cover adapted tov rest upon said globe and provided with an opening intersectedl by said holderV andV having its marginpartially de#4 sii4 finedV by a flat surface juxtaposed to the flatV f surface of said holder when' the cover rests'.-

uponl the globe. Y

2. In' a lighting fixture, a holder, said holder being fashioned intermediately of-its ends with a. substantially vertical flat surface, a cover provided with an opening intersected ly defined by a flat surface juxtaposed te thel flat surface of said holderv whenthe cover rests upon the globe and ineans comprising a yieldingly engageable projection on one of said flat surfaces for r-esisting displacement of said cover.

3. In a lighting fixture, a holder, a covery provided with an opening intersected by said holder, means consisting of juxtaposed flat surfaces on said holder and eoverrespeetively for preventing relative turning movement and meansincluding a yieldable catch on said rmember adapted to be contacted by the edge of the opening insaid cover for deterring upwardmovement ofthe latter. I

4. In an article of the character described,
